The Pennsylvania Department of Environmental Protection is raising “significant” concerns with a proposal to mine 200 feet deeper at Hanson Aggregates’ Oak Hall Quarry, State College, PA.
Technical deficiencies cited by the department could put that plan in jeopardy, reports State College.com.
The Department of Environmental Protection has given Hanson Aggregates until Friday, May 26, to address its concerns on potential sinkholes and risks to Spring Creek. The creek runs adjacent to the limestone quarry.
The department is considering the inclusion of a permit condition that would allow for mining only 50 feet deeper, the newspaper reports.
Jeff Sieg, director of corporate communications, Lehigh Hanson, parent company of the quarry operator, said Hanson “will continue working with the Department of Environmental Protection to address their general comments and technical deficiencies identified” in the application. The company will respond “within the requested timeframe,” he said.
